Conventional tests to determine modulus of elasticity are usually associated with the effects of loadings of very short duration. However, continually increasing load during the early age can produce an increase in the modulus of elasticity due to a

Sealed cement paste specimens (water/cement ratio 0.5), loaded at 28 days to a constant stress/strength ratio of 0.2, were subjected to cyclic temperatures of 90° to 23°F (32.2° to —5°C) and their creep behavior was studied in relation to the a

Wood-frame walls with low and high water vapour permeance insulating sheathings were tested in a climate simulator with respect to moisture and thermal performance. Exfiltration of moist interior air through the walls was simulated by pumping moist a

Describes uniaxial creep tests on Portland cement paste specimens at sub-zero temperature. During the course of the tests the stress-strength ratio was maintained constant by continuously increasing the applied load. Linearity was found to hold in lo

Concern has been expressed that recent increases in thermal insulation levels of residential basements in areas of seasonal frost may increase the risk of damage to foundations due to frost heave and adfreezing of the soil to the foundation wall. An

An investigation was undertaken to determine the levels of house depressurization against which naturally vented gas-fired furnaces and domestic water heaters can establish and maintain safe venting of combustion products. Also investigated were the

A method for evaluating the performance of air barrier systems for building enclosures is described. It is proposed that two identical enclosure elements be placed back-to-back and, for airtightness purposes, be joined to each other by the same techn
